T.O.P sonic

Topsonic offers complete solutions for monitoring, recording and analyzing noise. These systems reliably measure sounds and noises and attribute them individually to specific origins (e.g. an aircraft, vehicle or any other distinct source). The measurements are taken continuously and thus provide a permanent record of all noise events.

Topsonic’s product portfolio features systems for monitoring and assessment of noise for:

- Aircraft / flight track
- Environmental
- Industrial and construction

DataKustik, founded 1991,develops software for calculation and prediction of environmental, interior noise and air pollutant distribution as well as for building acoustics. Due to close cooperation with acoustical and software engineering experts powerful software products are developed, which are rich in features and in technical innovations.

DataKustic software includes:
- CadnaA for calculation, presentation, assessment and prediction of environmental noise.
- CadnaR for noise mitigation assessment and optimization based on psycho-acoustic parameters.
- BASTIAN to calculate airborne/impact sound transmission between rooms and from the exterior.

These softwares are successfully applied in more than 60 countries all over the world.
